I cant relink my Packs after a clean install

I had a bug some where on my computer so I did a clean install and manually replaced the software. I kept the folder 'Factory Packs' and replaced it after the install. However Ableton doesn't recognise any of them and I no longer have the installers.

It would take weeks to download all the orchestral samples again, is there a way I can relink? If I click on them or drag them into live it says there's no application to open them.
